Prominent leaders from the Christian right have warned Republicans they must do more to advance conservative values ahead of the US mid-term elections.

Their message to Congress, controlled by Republicans, is "must do better".

Support from about a quarter of Americans who describe themselves as evangelicals was a factor in President George W Bush's two election victories.

The Republicans will need to keep them onboard if they are to retain control of Congress in November.

At a news conference in Washington, some of America's most influential conservative leaders said the current perception among evangelical Christians was that the Republican majority was not doing enough for them.

Tony Perkins, president of the Family Research Council, said that apart from confirming two conservative judges to the Supreme Court, "core values voters" did not feel that Congress was advancing their interests.

The suicide pact.

The GOP doesn't get that they don't care about the realities to electoral politics. They folks on a mission and the GOP is their tool. If their insane stands causes losses of seats, so what? They're fighting for Satan God
